Display screens of electronic devices are generally classified into three types, LCD (Liquid Crystal Display), hard OLED (Organic Light Emitting Display), and flexible OLED.

The display screen is attached to the inner side of the cover plate, one side of the display screen displaying patterns faces the cover plate, the cover plate is transparent, and the patterns displayed by the display screen can be seen through the cover plate. The cover plate is used as a shell of the electronic equipment and is positioned on the outer surface of the electronic equipment. The display screen can also be attached to the outer side surface of the cover plate.

The curved display screen in the embodiments of the present application may employ flexible OLEDs. The width of the routing area (i.e., the black border) located at the edge portion of the display screen is visually recognizable and cannot be ignored, for example, the width of the black border of some display screens may reach 0.8 MM.

The overall shape of the electronic device can be flat plate, column, sphere, ring, helmet and the like. The largest display surface of the electronic device that presents content to a user when in use is defined as a major face and one or more surfaces connected to edges of the major face are defined as side faces. The angle between the major face and the side face is in the range 80 to 150 degrees, for example: 90 degrees. The main surface is polygonal and is provided with a plurality of straight edges, and the junction position of two adjacent straight edges is a corner part.

In the embodiment of the application, edge portions of the display screen are bent, so that most of the wiring areas are located on the side face of the electronic equipment, the area occupied by the wiring areas on the main face is reduced, the area of the displayable area of the main face can be increased, and customer experience is improved.

As shown in fig. 2 and 3, the curved display panel 1 includes a main display panel 11 and a plurality of side display panels 12, and the main display panel 11 is located on a main surface of the electronic device. The side display panel 12 shown in fig. 2 is not yet bent to the side of the electronic apparatus, and the curved display screen 1 has a flat plate-like structure as a whole. Two states are shown in fig. 3, the right drawing shows a state where the side display panel 12 is not yet bent to the side of the electronic apparatus, and the left drawing shows a state where the side display panel 12 is bent to the side of the electronic apparatus, but both of the drawings in fig. 3 are viewed from a perpendicular angle to the main display panel 11. After the side display panel 12 is bent to the side of the electronic device, the angle between the main display panel 11 and the side display panel 12 is in the range of 80 degrees to 150 degrees, for example: 90 degrees. The main display panel 11 may be used to display an image, and the side display panel 12 is not used to display an image, but both the main display panel 11 and the side display panel 12 may be used to display an image.

The cover plate can be of a box-shaped structure, the main display plate is attached to the bottom surface of the box-shaped structure, the side display plates are attached to the side surfaces of the box-shaped structure, and when the bottom surface of the cover plate is polygonal, the curved surface display screen located on the inner side of the cover plate is in a closed round-corner polygon or round-corner polygon-like shape on the whole when viewed from the outer side of the cover plate along the direction perpendicular to the bottom surface of the cover plate. Under the condition that the bottom surface of the cover plate is rectangular, the curved surface display screen positioned on the inner side of the cover plate is in a closed round-corner rectangle or similar round-corner rectangle shape as a whole when viewed from the outer side of the cover plate along the direction vertical to the bottom surface of the cover plate. In other words, when the bottom surface of the cover plate is polygonal, the curved display screen is in a shape of a closed rounded polygon or a rounded polygon as a whole in a direction perpendicular to the bottom surface. Under the condition that the bottom surface of the cover plate is rectangular, the curved surface display screen is in a closed round corner rectangle or similar round corner rectangle shape on the whole in the direction vertical to the bottom surface. The bottom surface of the cover plate substantially conforms to the shape and size of the main display panel.

Referring to fig. 2, the side of the main display panel 11 is a straight side 111, the main display panel has a plurality of straight sides 111, and a corner 112 is a portion where two adjacent straight sides 111 meet. A partial enlarged view of the area near the corner 112 is given in fig. 2, where D denotes the corner, and two parts a and B denote the side display panels 12.

Each straight edge 111 of the main display panel 11 is correspondingly connected with one side display panel 12, the edge where the side display panel and the straight edge are connected is the inner edge, and the position where the side display panel 12 is connected with the straight edge 111 can be set to be in the form of circular arc chamfer connection.

The edge of the side display panel 12 has the inner edge 121 and the outer edge 122, the outer edge 122 is located at the edge of the curved display panel 1, both the inner edge 121 and the outer edge 122 of the side display panel 12 are connected with the corner portion 112 of the main display panel 11, and a transition edge of a circular arc shape is connected with the corner portion 112 of the outer edge 122. The inner edge 121 may be a straight edge or a curved edge. The portion of the outer edge 122 located between the two circular arc-shaped transition edges may be parallel to the inner edge 121, and the portion of the outer edge 122 located between the two circular arc-shaped transition edges may also be non-parallel to the inner edge 121.

In any corner portion 112 of the main display panel 11, the curvature of the circular arc transition edges on both sides of the corner portion 112 may be equal or different.

In the enlarged partial view of fig. 2, the portions indicated by a and b are the arc-shaped transition edges, the arcs of the portions of the arc-shaped transition edges may be equal, and the arcs of the portions of the arc-shaped transition edges may also be unequal.

Since the curved display panel 1 has a certain thickness, the transition sides a and b of the circular arc shape in fig. 2 are formed as a circular arc line at each reference cross section, which is a cross section perpendicular to the thickness direction of the side display panel 12. The radian of each part of the circular arc line of the circular arc transition edge positioned on one reference section can be equal or unequal. The radian of the arc-shaped transition edges positioned on the arc lines of different reference sections can be equal or unequal.

The straight edge 111 of the main display panel 11 is an edge extending along a straight line. By straight edge is meant a straight line that extends, as viewed by the naked eye, and may have some curvature or curvature from a microscopic perspective.

As shown in fig. 3, the curved display panel is shown with patterns, and the left side of the figure shows that after the side display panel is bent to the side of the electronic device, only the corner 112 of the main display panel 11 has a black edge on the main surface of the electronic device, and the other positions have no black edge. Since the position where the straight edge 111 of the main display panel 11 is connected to the side display panel 12 is in the form of a rounded chamfered connection in the embodiment shown in fig. 3, the straight edge 111 and the corner portion 112 are not shown in the left drawing of fig. 3.

And as can be seen from fig. 3, the portion of the side display panel where the outer edge 122 is connected to the corner portion 112 is a circular arc-shaped transition edge, and when the side display panel is bent to the side of the electronic device, the corner portion 112 is very stretched and does not generate wrinkles. And, there is no unfilled corner in the corner of the said main display panel. The arc-shaped transition edge is in natural transition in vision, so that the edge lines of the main display panel 11 are smooth, and the use experience is improved. Although the display screen can be curved, it is difficult to bend in two or more directions at the same time due to technical limitations, and thus wrinkles are likely to occur in corners if the process is not appropriate. In this embodiment, the side display panel is bent along a straight edge, and since the corner portion is already the most marginal portion, and the portion of the outer edge of the side display panel connected to the corner portion is a transition edge of a circular arc shape, wrinkles do not occur.

As to why the side display panel is easily stacked at the corner portion and wrinkled when it is bent, a sheet of paper may be taken out, as shown in fig. 4 and 5, in which a sheet of paper is shown in fig. 4, four edges are bent in one direction along dotted lines, and it is found that an excessive amount of paper is generated at the corner portion, and an excessive amount of paper is a black portion. The excess paper is stacked and wrinkled.

In the embodiment of the present application, as shown in fig. 2, when the parts a and B are bent along the straight edge 111, there is no extra portion outside the point D because the arc-shaped edge is connected to the point D, and thus no wrinkle is generated at the point D.

Fig. 7 and 9 show a state in which the curved display screen is mounted on the electronic apparatus. The side display panel 12 located at the periphery of the main display panel 11 is bent to the side of the electronic apparatus such that the black side located at the side display panel 12 is located at the side of the electronic apparatus, and only the black side at the position of the corner portion 112 of the main display panel 11 is located at the main surface of the electronic apparatus, but since the position of the corner portion 112 is small, the black side at the corner portion 112 is also small. If only the main display panel located on the main surface of the electronic apparatus is used to display an image, substantially no black borders are visible on the main surface of the electronic apparatus, and substantially a full-screen is realized on the main surface, that is, the curved display screen located on the main surface is substantially a displayable area, and hardly any non-displayable black borders are visible.

Because the curved display screen has the arc-shaped transition edges on the two sides of the corner 112, the lines of the edge of the curved display screen are complete and continuous when viewed from the direction perpendicular to the main surface of the electronic device, and the curved display screen has natural transition and is smoothly unfolded. When the main display panel is polygonal, the curved display screen located inside the cover panel is in a closed rounded polygon or rounded polygon-like shape as a whole when viewed from the outside of the electronic device in a direction perpendicular to the main surface of the electronic device. When the main display panel is rectangular, the curved display screen located inside the cover panel is in a closed rounded rectangle or rounded rectangle-like shape as a whole when viewed from the outside of the electronic device in a direction perpendicular to the main surface of the electronic device. In other words, in the case where the main display panel is polygonal, the curved display panel is in the form of a rounded polygon or a rounded-corner-like polygon which is closed as a whole in a direction perpendicular to the main surface. In the case where the main display panel is rectangular, the curved display panel is in a form of a rounded rectangle or a rounded rectangle like a closed shape as a whole in a direction perpendicular to the main surface. The main display panel may be a polygonal plate, and more particularly, the main display panel may be a symmetric polygonal plate, for example: rectangular or hexagonal plate shape.

For a curved display screen with a side display panel bent to the side of the electronic device, the rectangular main display panel has four straight edges, two opposite straight edges are taken as a group, the side display panels connected to one group of straight edges can be symmetrically arranged, and the side display panels connected to the other group of straight edges can be symmetrically arranged or asymmetrically arranged.

As shown in fig. 7 and 9, fig. 7 and 9 show a complete electronic device, which is generally provided with a middle frame member 3, wherein the middle frame member 3 is used for fixing a cover plate and a rear case 4 of the electronic device. The middle frame piece 3 is of a frame-shaped structure, the cover plate and the rear shell 4 are respectively fixed on two sides of the middle frame piece 3, and the middle frame piece 3, the cover plate and the rear shell 4 jointly enclose a shell of the electronic device. The electronic equipment comprises a curved surface display screen and is characterized in that a circuit board and a power module are arranged in a shell of the electronic equipment, the power module is used for supplying power to the curved surface display screen and the circuit board, the circuit board is provided with a working circuit, the working circuit is used for sending a display instruction to the curved surface display screen, and when the curved surface display screen is in a working state, the main display board displays corresponding content according to the display instruction. When the curved surface display screen is in a working state, the side display panel can also display corresponding contents according to a display instruction sent by the circuit board. When the curved surface display screen is in a working state, the main display panel only has black edges at the corners. The straight sides of the main surface are located without black edges or with black edges only at the corners.

The middle frame piece 3 may also be provided as an integral structure with the rear shell 4.

The design of the middle frame part is generally related to the design of the cover plate, and two designs of the middle frame part and the cover plate are described as follows:

the first method comprises the following steps:

as shown in fig. 6 and 7, the curved display screen of fig. 6 has a pattern of a curved surface and has a black border, and in fig. 6, the curved display screen has been fixed to the inner side of the cover plate, so that the cover plate and the curved display screen are shown as two parts, but since the cover plate is transparent, the curved display screen can still be seen from the outer side of the cover plate. For ease of illustration, fig. 6 shows a front view, a top view, a bottom view, a left side view and a right side view. Fig. 7 is an overall configuration diagram of an electronic apparatus, and the electronic apparatus in the figure is a cellular phone. In fig. 7, a front view, a top view, a bottom view, a left side view and a right side view of the electronic device are shown. In fig. 7 the curved display screen, the cover plate, the middle frame part 3 and the back cover 4 can be seen, the cover plate being transparent so that the curved display screen can be seen from the outside of the electronic device.

As shown in fig. 6 and 7, the cover plate includes a bottom plate 21, a rounded portion 23, and a side plate 22, wherein an edge of the bottom plate 21 has a plurality of straight edges 211, and the side plate 22 is connected to the straight edges 211 of the bottom plate 21. The included angle between the bottom plate 21 and the side plate 22 is in the range of 80 degrees to 150 degrees, for example: 90 degrees. The connecting position of the side plate 22 and the straight edge 211 of the bottom plate 21 may be a circular arc chamfer connecting form. Since the position where the side plate 22 is connected to the straight side 211 of the bottom plate 21 is in the form of a rounded chamfered connection in the embodiment shown in fig. 6 and 7, the straight side 211 is not shown in the front view of fig. 6 and 7, and the straight side 211 can be seen in the top view, the bottom view, the left view, and the right view. Of course, the straight edge 111 of the curved display screen is not visible in the front view, and the straight edge 111 is visible in the top view, bottom view, left view, and right view.

The border position of the adjacent straight edge 211 of the bottom plate 21 is connected with the round corner part 23, and the round corner part 23 is a three-dimensional arc-shaped structure. The side plate 22 is connected to both sides of the rounded portion 23. The inner surface of the fillet 23 is an arc surface, the outer surface of the fillet 23 is also an arc surface, but the radians of the arc surface of the inner surface and the arc surface of the outer surface may be equal or unequal. The curvatures of the respective portions of the circular arc surfaces of the inner surfaces of the rounded portions 23 may be equal. The curvature of the portions of the arc surface of the inner surface of the fillet may also be unequal, for example: the radian of the central position is small, and the radian of the edge position is large, or the radian of the central position is large, and the radian of the edge position is small. The curvature of each portion of the arc surface of the outer surface of the fillet may be equal. The curvature of the portions of the arc surface of the outer surface of the fillet may also be unequal, for example: the radian of the central position is small, and the radian of the edge position is large, or the radian of the central position is large, and the radian of the edge position is small.

At the position of the round portion 23, a cross section along a direction parallel to the inner surface or the outer surface of the bottom plate 21 is a first round portion cross section. At the position of the rounded portion 23, the sections perpendicular to the two straight sides 211 connected to the rounded portion 23 are a second rounded section and a third rounded section, respectively.

The outer surface of the fillet 23 is an arc in each first fillet section, and the inner surface of the fillet 23 is an arc in each first fillet section. The outer surface of the fillet 23 is an arc in each second fillet section, and the inner surface of the fillet 23 is an arc in each second fillet section. The outer surface of the fillet 23 is an arc on each third fillet section, and the inner surface of the fillet 23 is an arc on each third fillet section.

As shown in fig. 6, the curved display screen is attached to the inner or outer side of the cover plate, specifically, the side display panel 12 is attached to the inner or outer side of the side panel 22 of the cover plate, the main display panel 11 is attached to the inner or outer side of the bottom panel 21 of the cover plate, the corner portion 112 is attached to a position where two adjacent straight edges 211 of the bottom panel 21 meet, and the corner portion 112 is located on a main surface of the electronic device. That is, the corner portion 112 of the main display panel 11 is not attached to the inner surface of the rounded portion 23, and the corner portion 112 is not bent according to the bending of the inner surface of the rounded portion 23, so that the corner portion 112 of the main display panel 11 is prevented from being bent in two directions if the inner surface of the rounded portion 23 is bent in two directions at the same time. The bottom plate 21 of the cover plate is matched in shape and size to the main display panel 11 so that the main display panel 11 is just covered on the whole bottom plate 21 and the bottom plate 21 has no surplus portion. For example: the bottom plate 21 of the cover substantially conforms to the shape and size of the main display panel 11.

The width of the side panel 22 of the cover panel may be equal to the width of the side display panel 12.

As shown in fig. 6 and 7, the width of the side panel 22 of the cover plate may be greater than the width of the side display panel 12, and an edge portion of the side panel 22 of the cover plate protrudes beyond an edge of the side display panel 12, so that, as shown in fig. 7, the edge of the side panel 22 of the cover plate is not easily touched to the edge of the side display panel 12 when assembled with the middle frame 3.

The bottom plate 21 may have a polygonal plate shape, specifically, the bottom plate 21 may have a symmetrical polygonal plate shape, for example: rectangular or hexagonal plate shape. Generally, the shape of the chassis base 21 corresponds to the shape of the main display panel 11. For example: if the main display panel 11 is rectangular, the shape of the bottom plate 21 is generally rectangular.

The straight edge 211 of the bottom plate 21 is an edge extending along a straight line. The straight edge is a straight line which is seen by naked eyes, and a certain bending or arc shape can exist from a microscopic angle.

In this embodiment the centre frame piece 3 comprises a plurality of elongated sides 31, which elongated sides 31 are connected together to enclose a frame. The side plate 22 of the cover plate is assembled with the side edge 31.

And the second method comprises the following steps:

as shown in fig. 8 and 9, the right side of fig. 8 shows a perspective view of the unfolded display panel (in this case, the display panel has a flat plate-like structure as a whole), and the left side shows a perspective view of the display panel after being bent and attached to the inner side of the cover plate, and the shape and size of the curved display panel substantially correspond to those of the cover plate. Fig. 9 is an overall configuration diagram of an electronic apparatus, and the electronic apparatus in the figure is a cellular phone. Fig. 9 shows a front view, a top view, a bottom view, a left side view, and a right side view of the electronic device. In fig. 9 the curved display screen, the cover plate, the middle frame part 3 and the back cover 4 can be seen, the cover plate being transparent so that the curved display screen can be seen from the outside.

The curvature of each portion of the inner surface of the wrap angle portion 32 may be equal. The curvature of the various portions of the inner surface of the wrap angle portion 32 may also be unequal, for example: the radian of the central position is small, and the radian of the edge position is large, or the radian of the central position is large, and the radian of the edge position is small. The curvature of each portion of the outer surface of the wrap angle portion 32 may be equal. The curvature of the various portions of the outer surface of the wrap angle portion 32 may also be unequal, for example: the radian of the central position is small, and the radian of the edge position is large, or the radian of the central position is large, and the radian of the edge position is small.

At the position of the fillet 32, a cross section along a direction parallel to the main surface of the electronic apparatus is a first fillet cross section. At the position of the corner 32, the sections perpendicular to the longitudinal direction of the two edges 33 connected to the corner 32 are a second corner section and a third corner section.

The outer surface of the wrap angle portion 32 is curved in each first wrap angle section, and the inner surface of the wrap angle portion 32 is curved in each first wrap angle section.

The outer surface of the fillet 32 is curved in each third fillet section, and the inner surface of the fillet 32 is curved in each third fillet section.

As shown in fig. 8 and 9, the cover plate includes: a bottom wall 24 and a plurality of side walls 25, the bottom wall 24 being located on a main face of the electronic device, the side walls 25 being located on side faces of the electronic device. The angle between the bottom wall 24 and the side wall 25 is in the range of 80 to 150 degrees, for example: 90 degrees. The edge of the bottom wall 24 has a plurality of straight edges 241, and each straight edge 241 is connected to one of the side walls 25. The position where the side wall 25 is connected to the straight edge 241 of the bottom wall 24 may be provided in the form of a rounded chamfered connection. Since the position where the side wall 25 is connected to the straight edge 241 of the bottom wall 24 is in the form of a rounded chamfered connection in the embodiment shown in fig. 8 and 9, the straight edge 241 is not shown in the front view of fig. 9, and the straight edge 241 can be seen in the top, bottom, left and right views. Of course, the straight edge 111 of the curved display screen is not visible in the front view, and the straight edge 111 is visible in the top view, bottom view, left view, and right view.

The radian of each part of the circular arc-shaped transition edge can be equal, and the radian of each part of the circular arc-shaped transition edge can also be unequal.

Because the side wall 25 has a certain thickness, the circular arc-shaped transition edge is a segment of circular arc line on each first cross section, and the first cross section is a cross section perpendicular to the thickness direction of the side wall 25. The radian of each part of the arc-shaped transition edge positioned on the arc line of one first section can be equal or unequal. The radian of the arc-shaped transition edges positioned on the arc lines of different first sections can be equal or unequal.

The bottom wall 24 may be a polygonal plate, specifically, the bottom wall 24 may be a symmetric polygonal plate, such as: rectangular or hexagonal plate shape. Generally, the bottom wall 24 is shaped to conform to the shape of the main display panel 11. For example: if the main display panel 11 is rectangular, the bottom wall 24 is also generally rectangular in shape.

The straight edge 241 of the bottom wall 24 is an edge extending along a straight line. The straight edge 241 is a straight line which can be seen by naked eyes and can have a certain bending or arc shape from a microscopic angle.

For the cover plate with the rectangular bottom wall 24, the bottom wall 24 has four straight edges 241, two opposite straight edges 241 are taken as a group, the side walls 25 connected to one group of straight edges 241 may be symmetrically arranged, and the side walls 25 connected to the other group of straight edges 241 may be symmetrically arranged or asymmetrically arranged.

The bottom wall 24 of the cover plate is matched in shape and size to the main display panel 11 so that the main display panel 11 is just covered on the whole bottom wall 24 and there is no extra part of the bottom wall 24. For example: the bottom wall 24 of the cover substantially conforms to the shape and size of the main display panel 11.

The cover plate is assembled with the middle frame, wherein the corner wrapping part 32 of the middle frame 3 is fixed with the cover plate corner part 242 of the cover plate, and the edge covering 33 of the middle frame 3 is fixed with the side wall 25 of the cover plate. The width of the side wall 25 of the cover plate may be equal to the width of the side display panel 12, so that the middle frame member 3 may fix the side wall 25 of the cover plate and the side display panel 12 of the curved display screen.
